MoonTime

MoonTime shows cooldowns and durations of DoTs and eclipse in a compact way in the center of the screen:

The default layout consists of four tiny frames showing all essential information of the moonkin-rotation

Duration of moonfire and insect swarm on the target
Duration and cooldown of the active lunar or solar eclipse
Cooldown of starfall
The Layout noBrain shown what key to hammer. Don't stop the casting, it just tells you what button to press.

The priority is IS>MF>Starfire (while Lunar and before Solar)>Wrath which leads to a 'always refresh dots and standard eclipse use'-rotation
Two additional frames show the cooldowns of Starfall and Treants
Type /moontime or /moon to configure the addon
